This command will read ten Gigabytes from the source drive and write that to a file called driveimage.dd.aa. It will also calculate the [[MD5]] hash and the sha256 hash of the ten Gigabyte chunk. It will then read the next ten gigs and name that driveimage.dd.ab. The md5 hashes will be stored in a file called md5.txt and the sha256 hashes will be stored in a file called sha256.txt. The block size for transferring has been set to 512 bytes, and in the event of read errors, dcfldd will write zeros.
